allows control of the "burnability" of raw mix--the ability of the kiln to produce the desired compound composition.
Now, we have a control parameter (a), which relates the ratio of [C.sub.3]A to [C.sub.4]AF; a control parameter (f), which relates to the ratio of [C.sub.3]S to C2S; and a control parameter (R), which relates to burnability and fuel consumption.
